ENIG versus electrolytic hard gold: intended use
Compare ENIG and electrolytic hard gold by pad function, contact wear, coverage drawings and acceptance evidence rather than gold color alone.

What controlled-flow prepreg is intended to control
Understand controlled-flow prepreg through bond-region geometry, resin intrusion limits and a rigid-flex clearance example that identifies missing evidence.
